MatchMakerStub - make it work & add test

The super() in MatchMakerStub.__init__ was
referencing the wrong class due to copy/paste.

I've also added a test for this class.

Move wsgi module to deprecated package

As we are planning to deprecate the wsgi module, move it
out of the main openstack/common folder to the new
"deprecated" folder.

Move some of the middleware classes into the middleware
package, since those are still useful and should be
maintained.

There's still work to do to remove the dependency of the
size limit middleware on the Request class in the now
deprecated wsgi module.

Refer to the mailing list thread at
http://lists.openstack.org/pipermail/openstack-dev/2013-May/009666.html
for additional details.
